Saia® Energy counters – accelerated from 0 to 250
The new two-way energy meters
With the new Saia Two-Way Energy Counter family, bidirectional flow of electrical en-
ergy can be measured and counted with a single device, as. This new two-way meter is
particularly at home where energy is consumed and produced in a single location, such as
a photovoltaic energy facility.
The new two-way meters are direct measuring devices available in a one- and three-
phase design, and in a three-phase design for a measuring current transformer.
The first two-way counters will be available as S0 and S-Bus versions.
After the pilot phase the M-Bus and Modbus interfaces will be integrated
to ensure the full communication capability of the two-way counters.
The new two-way counters can be used in the same way as previous energy counters via the
bus connection for active energy monitoring and management. The bus connection from
the energy counters to the Saia® PCD devices or the S-Energy Manager create easy access to
the data measured by the electricity meter, so it can be processed, displayed and analyzed.

The whole family Saia® Energy Meter is available as a MID-
approved version. MID (Measuring Instruments Direc-
tive) is the colloquial name for the 2004/22/EC European
Union Directive on measuring instruments. With its
MID-approved energy counters, Saia® offers precision
from its factory in Murten. Thus energy counters are
approved for use throughout Europe without the need
for additional calibration.

A typical use
for two-way energy counters
On the roof, photovoltaic cells convert
the sun’s rays into electrical power, or
wind drives the rotor blades of a wind-
mill. Excess energy that is not consumed
is normally fed into the national grid.
An electric car runs on self-generated
energy. If there is a demand for balanc-
ing power in the national grid, the en-
ergy stored in the electric car is used as
a buffer.
Its battery serves as a reservoir to
compensate for fluctuations in the main
supply.
